[ Performance Testing ]

For testing purposes we installed these OCZ ZX Series power supplies into a rather power hungry gaming system sporting a pair of GeForce GTX 480 SLI graphics cards. In the past we have tested high-end power supplies on our Core i7 965 test system, though this time we are going to use the Core i7 980X test system. Test System Specs Hardware - Intel Core i7 980X @ 4.0GHz - x3 2GB G.Skill DDR3 PC3-12800 (CAS 9-9-9-24) Module(s) - x2 Samsung 1TB 7200-RPM (Serial ATA300) - Nvidia GeForce GTX 480 (1GB) - Nvidia GeForce GTX 480 (1GB) - ASUS P6T Deluxe (Intel X58) Software - Microsoft Windows 7 Ultimate (64-bit) - Nvidia Forceware 258.96 WHQL Furthermore, we have overclocked the six-core Core i7 processor, causing it to not only run faster, but also consume considerably more power. The overclock saw the default 3.33GHz operating frequency pushed to a lightning fast 4.0GHz! In addition, a few other devices were plugged in for the ride. These included a total of two 1TB hard drives, four large case fans, a water-cooling system, 6GBs of memory, and a single DVD-RW. As you will see in our test measuring the amount of power being drawn from the wall, almost all reached 800 watts when under full load, while the EVO_Blue 750w unit exceeded this hitting 802 watts. At idle the system still sucked down an impressive 403 watts when using the EVO_Blue 750w, while the OCZ ZX Series units were more conservative using around 390watts. Imagine what this system could do to your power bill if run 24/7. Despite using the world’s most powerful desktop processor in conjunction with two extreme graphics cards, the OCZ ZX 850w had no problem with our stress tests. Despite being very quiet even when under full load, the OCZ ZX Series remained very cool as all three units operated at less than 40 degrees. The idle temperatures were also very good and were only a few degrees higher than the ambient room temperature. The performance of the OCZ ZX series was excellent, as the voltages did not vary greatly when under load. The stress test results were recorded running Prime95 along with Furmark running. Both programs were able to maintain a constant CPU and GPU utilization level of 100% while using various other system devices. Furthermore, a number of the hard drives were being accessed at the same time via other networked computers. This had virtually no impact on the power supply's performance over several hours of hard usage.

Posted on: 06/30/2011 11:30 AM Great looking quality power supplies. If they made a 650w version or thereabouts I would snap it up in a heart beat! Nice work on the review and great images. Also thanks for opening it up.

Stuff like memory, hard drives and even motherboards are so cheap now yet high quality power supplies are like SSD's.
